Why are five-star base office chairs more common in the office than three legs and four legs ones?
1, While the office chairs in the five-star base will be very stable on uneven ground, the three-legs one will tilt, and the four-legs one will shake.
2, This kind of five-legs of chair generally has casters. The weak link of the casters is the bearing. The more wheels there are, the smaller the weight distributed on each bearing, and it will be more durable.
